Thanks for writing in. I can't be certain what you need without seeing photos of your old hardware, but take a look at either our 39-138 or 39-141. Look over the dimensions listed on the product page and see if one of these is what you're looking for. If not, we will need pictures of your old operator out of the window, with the link arm(s) in full view. Many thanks. |
